University of Stuttgart.
* Telescopic Camera for Phaethon (TCAP) — The telescopic camera has a mass of 15.8 kg.
* Multiband Camera for Phaethon (MCAP) — The multiband camera has a mass of 3.5 kg and will detect light in 390 nm, 550 nm, 700 nm, 850 nm
wavelength
In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, t ...
